How can one determine the pH of a weak acid?
To determine the pH of a weak acid, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak acid and its dissociation constant.
How do you test pH of strong acid?
To test the pH of a strong acid, you can use a pH meter or pH test strips. Make sure to handle the acid carefully and wear appropriate protective equipment. Dip the pH meter probe into the acid or dip the pH test strip into the acid and compare the color change to the pH color chart to determine the pH level.
How can one determine whether a substance is a strong or weak acid?
One can determine whether a substance is a strong or weak acid by looking at its ability to fully dissociate in water. Strong acids completely dissociate into ions in water, while weak acids only partially dissociate. This can be measured by looking at the pH level of the solution - strong acids have a lower pH than weak acids.
Is pH12 a strong acid?
No, pH 12 indicates a strong base, not a strong acid. A strong acid would have a pH value below 7.
How does pH affect titration?
pH plays a crucial role in titration as it helps determine the endpoint of the reaction. The pH at the equivalence point depends on the acid-base reaction being titrated. For strong acid-strong base titrations, the pH at the equivalence point is 7; for weak acid-strong base titrations, the pH is greater than 7; and for weak base-strong acid titrations, the pH is less than 7. pH indicators can also be used to visually show the endpoint of the titration based on color change.

How can you determine if a substance is a strong acid?
A strong acid is a substance that completely dissociates in water to produce a high concentration of hydrogen ions. You can determine if a substance is a strong acid by testing its ability to fully ionize in water and produce a low pH level below 7.
What is the pH score for a strong acid and a strong base?
A strong acid will have a low pH and a strong base will have a high pH.
Is pH 2.1 a strong or weak acid?
It's considered a dilute acid, not a weak acid. That term has a very specific meaning. A strong acid is one that ionizes (many chemistry texts use the word "dissociate") completely in water, and a weak acid is one that doesn't completely ionize. Hydrochloric acid is a "strong" acid; hydrofluoric acid is a "weak" acid even though it's more corrosive than hydrochloric acid is. So...you could take hydrochloric acid (a strong acid) and mix it with a lot of water, get it up to pH 6, and still have a strong acid.
What should be pH -value to be strong acid?
The pH will depend on the concentration of the acid, not on whether it is strong or weak.
What is pH number of strong acid?
A number less than a pH of 4 indicates a strong acid.
What should be pH value to be strong acid?
The pH will depend on the concentration of the acid, not on whether it is strong or weak.
How do you find out how strong an acid is use?
One way to determine the strength of an acid is by looking at its pH level. The lower the pH value, the stronger the acid. Another method is by measuring the acid's dissociation constant (Ka); the higher the Ka value, the stronger the acid. Additionally, you can also observe the acid's reactivity with other substances or its ability to donate protons to gauge its strength.
